BUG? Parallels 6 prevent Mac OSX to sleep/standby while running VMs

Parallels 6 ( but also with 5 afaik with trial key) with active VMs Mac OSX do not sleep when reach idle time set in energy preferences. No messages appear in console. This is a BIG problem for portable Macs running on batteries.
Any workaround? or when this will be corrected? ( if it is a confirmed bug )
Thank you.

 

Lack of "auto sleep", too

I can sleep my iMac running Parallels 6 with XP manually. It will not enter sleep automatically per "Energy Saver" in System Preferences when in COHERENCE mode. Coherence is otherwise great. Hopefully there will be a fix soon.

 

I am having the same problem with Parallels 6, in Full Screen. To sleep is somehow basic functionality ... it is a bit unexpected that something like this fails. On the bright side there have been various improvements in the last update to Parallels 6. I look forward for a fix now to this failure in allowing the machine to sleep.

 

I am looking foward to automatic sleep since more than a year. Maybe the implementation of such a thrilling feature just needs some time for the developers.
